Effect of two different techniques of arteriovenous fistula puncture on wound infection in haemodialysis patients.

Safe and effective arteriovenous fistula (AVF) puncture is very important to reduce the wound complications of haemodialysis (HD). For AVF puncture in dialysis patients, there is a lack of clarity and consistency regarding the relative advantage of buttonhole (BH) over rope-ladder (RL) cannulae in terms of wound complications. The study was published in several scientific databases including Cochrane Library, PubMed and Embase by October 2023. Data from all controlled trials looking at the effect of BH and RL on wound complications in haemodialysis patients were included. The articles were written in English, and they were about adult who had AVF while on dialysis. Studies with or without BH or RL treatment were excluded from the analysis. The data was analysed with RevMan5.3 software. Out of 215 trials, 9 were chosen for the final analysis. The study publication dates were between 2000 and 2023. Of these, 17 326 patients received AVF therapy. Among them, there were 3070 BH and 14 256 RL. In 9 studies, RL had a lower risk of postoperative wound infection compared to BH (OR, 3.38; 95% CI, 3.06, 3.73 p < 0.0001); In all 3 studies, there were no statistically significant differences in the risk of post operative bleeding in RL versus BH(OR, 0.76; 95% CI, 0.25, 2.33 p = 0.63). Our studies have demonstrated that RL trocars are superior to BH trocars in the prevention of wound infection.

The effect and safety of Bushen Huoxue Method combined with cyclophosphamide in the treatment of systemic lupus erythematosus: A protocol for systematic review and meta-analysis.

BACKGROUND: Systemic lupus erythematosus (SLE) is an autoimmune disease that involves multiple systemic organs. Bushen Huoxue Method (BSHXM) is a traditional Chinese medicine treatment, which is used for the treatment of SLE combining with cyclophosphamide. However, no systematic review has been performed to describe its effectiveness. This study provides a protocol for systematic review and meta-analysis of currently published randomized controlled trials (RCTs) reporting the combination of BSHXM and cyclophosphamide for the treatment of SLE, thus providing evidences to support clinical practice. METHODS: RCTs reporting the combination of BSHXM and cyclophosphamide for the treatment of SLE before October 2022 will be searched in the online databases, including the PubMed, Cochrane, Embase, Web of Science, CNKI, Wanfang, VIP databases and CBM. The Cochrane Risk of Bias 2 (RoB2) tool will be used to evaluate the quality of included RCTs. Meta-analysis will be performed using Stata 14.0. RESULTS: Results to be published in a peer-reviewed journal providing evidence for the efficacy and safety of the combination of BSHXM and cyclophosphamide on the treatment of SLE. CONCLUSIONS: This study will provide a strong basis for the effectiveness and safety of the combination of BSHXM and cyclophosphamide on the treatment of SLE.

The efficacy of combined therapy of qingfeiPaidu capsule and lianhuaqingwen capsule nursing interventions for hospitalized patients with COVID-19: A retrospective study of medical records.

Coronavirus disease-19 (COVID-19) caused a global pandemic burden, affecting hundreds of thousands of individuals, having life-threatening outcomes. Traditional Chinese Medicine plays a crucial role in the treatment of patients with COVID-19. The purpose of this study was to investigate the efficacy of combined therapy of qingfeiPaidu (QFPD) capsule and lianhuaqingwen (LHQW) capsule nursing interventions in the treatment of patients with COVID-19. A total of 318 patients with COVID-19 were enrolled and randomly received QFPD (n = 106), LHQW (n = 106), and QFPD-LHQW (n = 106). The clinical characteristics of COVID-19, the total lung severity scores, and blood laboratory indices were recorded in each patient in each group before treatment and at the end of treatment. The outcomes demonstrated that QFPD-LHQW group shortened the length of hospitalization, decreased C-reactive protein, creatine kinase, creatine kinase-myocardial band, lactate dehydrogenase, and blood urea nitrogen levels, and improved clinical symptoms, pulmonary inflammation, and prognosis. At the end of treatment, inflammation, immune function, circulating white blood cells, total lymphocyte count, and glutamic-oxaloacetic transaminase levels improved dramatically in 3 groups compared with baseline. All patients met the discharge criteria after 30-day treatment in 3 groups. Combined therapy of QFPD and LHQW demonstrated significant anti-inflammatory effects compared with those of only QFPD or LHQW in patients with mild and moderate COVID-19. The combined therapies may alleviate clinical symptoms of COVID-19 patients by improving inflammation and immune function.

[Impact of subchronic exposure to low-dose nano-nickel oxide on the reproductive function and offspring of male rats].

OBJECTIVE: To investigate the influence of subchronic exposure to low-dose subchronic nano-nickel oxide (NNO) on the reproductive function of male rats and embryonic development of the pregnant rats. METHODS: Fifty normal healthy male SD rats weighing 180－220 g were randomly divided into five groups of equal number, negative control, 4 mg/ml micro-nickel oxide (MNO), and 0.16, 0.8 and 4 mg/ml NNO, those of the latter four groups exposed to MNO or NNO by non-contact intratracheal instillation once every 3 days for 60 days, and then all mated with normal adult female rats in the ratio of 1∶2. After the female animals were confirmed to be pregnant, the males were sacrificed and the weights of the body, testis and epididymis obtained, followed by calculation of the visceral coefficients, determination of epididymal sperm concentration and viability and the nickel contents in the blood and semen by atomic fluorescence spectrometry. The female rats were killed on the 20th day of gestation for counting of the implanted fertilized eggs and live, dead and resorbed fetuses. RESULTS: After 60 days of exposure, the rats of the NNO groups showed no statistically significant differences from those of the negative control and MNO groups in the weights of the body, testis and epididymis or visceral coefficients. Compared with the negative control group, the animals of the 0.8 and 4 mg/ml NNO groups exhibited markedly decreased sperm concentration (ï¼»9.36 ± 0.98ï¼½ vs ï¼»7.49 ± 1.46ï¼½ and ï¼»6.30 ± 1.36ï¼½ ×106/ml, P < 0.05) and viable sperm (ï¼»85.35 ± 9.16ï¼½% vs ï¼»68.26 ± 16.63ï¼½% and ï¼»65.88 ± 14.68ï¼½ %, P < 0.05), increased morphologically abnormal sperm (ï¼»8.30 ± 2.47ï¼½% vs ï¼»13.99 ± 4.87ï¼½% and ï¼»15.38 ± 8.86ï¼½ %, P < 0.05), and elevated rate of dead and resorbed fetuses (1.18% vs 6.89% and 7.37%, P < 0.05), blood nickel content (ï¼»0.13 ± 0.16ï¼½ vs ï¼»0.52 ± 0.34ï¼½ and ï¼»0.82 ± 0.44ï¼½ mg/L, P < 0.05) and semen nickel content (ï¼»0.08 ± 0.13ï¼½ vs ï¼»0.35 ± 0.23ï¼½ and ï¼»0.63 ± 0.61ï¼½ mg/L, P < 0.05). The nickel level in the semen was correlated significantly with that in the blood (r = 0.912, P <0.01), negatively with the rate of viable sperm (r = －0.879, P <0.01) and positively with the percentage of morphologically abnormal sperm (r = －0.898, P <0.01). CONCLUSIONS: Sixty-day exposure to nano-nickel oxide at 0.8 and 4 mg/ml can produce reproductive toxicity in male rats and result in fetal abnormality in the females, while that at 0.16 mg/ml has no significant toxic effect on the reproductive function of the males.
